this art. As the specific construction of the recorder-rcproducer and ofthe feeding mechanism therefor constitutes no part of my presentinvention, the details are not illustrated.

in the construction shown the mandrel is driven by means of a wheel 5which is loose on the mandrel shaft but which can be operativelyconnected therewith by means ofv a jaw clutch 6. This clutch can bethrown into and out of operation in any of the well known ways, it beingpreferably opened and closed manually. For rotating the wheel 5 asuitable motor is pro\"ided,-

this motor in the preferred construction being an electric motor asindicated at 7 in the drawings. This motor is connected with the wheel.by a suitable power transmitting device such as the leather belt 8.

The motor is provided with. a suitable device for starting and stoppingit, and in the case. of an electric motor, such as here shown, thestarting and stopping device is a. suitable switch. f

Connected with the recr rder-reproduc preferably by means of a. longflexible tutti 5) is a mouth-piece 10 into which the dictator talks.This mouth-piece is movable vertically with respect to thcrecorder-reproduced and a suitable support for it is provided forholding it in a definite predetermined inopcrativc position. Inaccordance with my invention this support for the uuiuth-piece ismechanically connected \vithtlie start and stop mechanism for the rmotor, in this case the switch, so that the motor is started when themouth-pie is removed from its support am. stopped when the mouthpiece isreturned to its support.

In the construction illust 'ated use made of the horizontal bar 1ivwhich provided on dictaphones for carrying the scale which. indicatesthe position of the recorder-reprmlucer. Secured to this bar is 12having a recess with walls adapted to fit the top and side surfaces ofthe bar. Extending through. the bottom of the bracket is a set screw 13adapted. to engage the inner side of the bar and lock the bracket inplace.

The bracket 12 is provided with two pairs of cars leis-ll and l515-between which extends a hook lever 16. This hook lever is preferablyformed of" sheet metal doubled its upper end to the rear the sake ofconvenience and simplicity, this switch 19 is secured to an arm 20formed integrally with the bracket 12. The switch can be of any suitableconstruction but I prefer a switch having a cylindrical casing andhaving 'a plunger working therein. Suitable contacts are carried by thecasing and the plunger so that the circuit is completed when the plungeris in its lower position and broken when the plunger is in its upperposition. Suitable electrical connectrons are provided between theswitch 19 and the motor 7, these not being shown in detail as they willbe obvious to those familiar with electrical constructions.

For operating the plunger of the switch 19, I provide a link 21pivotally connected at its lower end to the plunger and pivotallyconnected at its upper end to the hook lever 16, as indicated at 22.Connected to thehook lever 16 is a spring 23 which tends to throwtherear end of the lever downward, thus throwing the switch into itscircuit making position. Preferably this spring is a coil tension springconnected at part of the lever and at its lower end to the arm 20. The

3 spring 23 is of such strength as to throw ished dictating,

the switch into operative position when the weight of the mouthpiece andspeaking tube is not carried by theforward end of the lever. But whenthe mouth-piece is carried by the forward hooked end of the lever, thetension of thespri'ng 23 is overcome and the switch 19 is opened.Preferably there is provided a set screw which extends upward betweenthe two ears 15l5 of the bracket and serves a stop to limit the downwardmovement of the lever 16, thus preventing the transmission totheswitchof the weight of the mouth-piece and speaking tube. This set screw isindicated in the drawing by 21 and it is preferably adjustable.

From the foregoing description, it will be understood that the user ofthe talking machine need give no attention to the motor. Vhen he desiresto dictate it is only necessary for him to pick up the speaking tube andstart talking. When he has finit is only necessary for him to hang upthe mouth-piece and speaking tube and the motor automatically stops. Itwill of course be understood that the opera- I sold as a tor may, andpreferably does, make use 01 the mechanical clutch 6 above referred tofor stopping and starting the mandrel and 'the record independently ofthe motor when he desires to stop dictating for a moment only.

The switch and the pivoted mouth-piece supporting lever connectedtherewith, together with the supporting bracket and other partsillustrated in the drawing are well adapted to be made and soldindependently of the other parts of the talking machine, and are capableof being applied to talking machines already in thehands of users andnot originally provided with an automatic start and stop mechanismembodying my invention. My invention is therefore to be understood amechanism whether manufactured and sold separately orwhethermanufactured and part of a complete talking machine.
